Overall, I did think this was a somewhat confusing article to read, but I found a few things interesting. One thing that stuck out to me was an idea about how TV is believed to be represented.
In 'Encoding/Decoding' it is stated 'that representations of violence on the TV screen are not violence but messages about violence'. Do you agree or disagree with this concept? What are some examples of TV shows that back up your belief?

I don't think it is just one or the other, I believe that it depends on the show and how a certain person views it personally. For example, any Law & Order shows might be the type that send a message about violence because you see the person who does something bad and they are punished for their actions, whereas other shows like Supernatural have violence but really no message. So once again, I think a lot of it depends on how an individual sees it.
I agree with the previous statement. TV has a tendency to show violence, but there is always a reason behind it, whether it be for entertainment or as a kind of warning. In a very extreme example, Degrassi: The Next Generation showed a school stabbing, in which a prevalent character died. While it was for the story of the show, it was also to warn or send a message out about bullying and the like.
